Blower Motor Assembly
Genuine Lg part
By: Lg
Part Number: ABT35083801

The Blower Motor Assembly is an OEM replacement part for LG dishwashers. Located inside the wash cavity, it functions to distribute heated air throughout during the dry cycle. Rapid rotation of the blower motor blades works to eject moisture from dishes and ensure thorough drying. 

Causes of a bad blower motor include failure of the motor itself, cracks in the blades that disrupt airflow, or bearing issues preventing proper rotation.

Symptoms include:

  • Dishes still feeling damp after a cycle 
  • Puddles of water remaining in the bottom of the dishwasher
  • Water droplets on upper racks/dishes
  • The motor producing grinding/squealing noises on startup

It is also compatible with some Kenmore dishwashers using LG components. 

This part fixes the following symptoms
  • Not drying dishes properly

Do-It-Yourself Stories from Customers like You Water leak   Art D. • Souderton , PA • May 27, 2014

The solenoid that opened the air vent for drying was broken so it was open during the wash cycle allowing water to escape into the air duct. Found the part at SearsParts and AppliancePartsPro, and Sears was $15 more expensive. I ordered on Friday from AppliancePartsPro and selected standard shipping and the part arrive the next day (Saturday). Amazing service. AppliancePartsPro will be my first stop in the future.

Do-It-Yourself Stories from Customers like You Lg dishwasher “ne” or “ue” error code (vario spray arm).   Dimitri T. • Cranston , RI • February 26, 2019

This was a very simple repair. It was done in about an hour. It involves disconnecting the dishwasher, emptying the water from the inside, taking it out and flipping it over, and replacing the diverter motor. This repair is done on the underside of the dishwasher, nothing to disconnect inside (just remember to remove the baskets). It would be wise to order the motor seal and micro switch that goes with it as they are all cheap parts and easy to swap out during the procedure. Be sure to take... Read more
